The Bitcoin boom has generally gone bust, and as a result, we just don't hear as much about cryptocurrency as a major market mover as we used to. The value of Bitcoin and other cryptocurrencies crashed last summer, leaving many investors hurting and lots of crypto mining rigs with expensive GPUs running idle and unused. The good news for gamers is that the crash of crypto meant graphics cards were finally available at reasonable prices. Further, a new report has been published today that throws more shade on the legitimacy of Bitcoin trading as a currency itself. The analysis was published by Bitwise this week and found that unregulated currency exchanges actually fake 95% of Bitcoin... Read more...
Hold onto your wallet. Researchers at ESET have discovered the first known instance of a relatively new strain of cryptocurrency-stealing malware, called a "clipper", on the Google Play Store. They reported their findings to the Play Store's security team on February 1st, who quickly took down the offending application. The attack uses a remarkably simple trick to part users with their digital funds. Cryptocurrency values are assigned to a long, unique string of characters known as a wallet. In order to make a transaction, a sender typically needs to enter the recipient's wallet address in their app. This is similar to how you would put a real-world address on an envelope in order for it to be...

If you've invested heavily in cryptocurrencies like Bitcoin and Ethereum over the past year, you probably need a stiff drink right about now. The cryptocurrency "boom" is no more, and values are heading south, much to the chagrin of crypto miners that thought mining with off-the-shelf [and custom] hardware would bring them digital fortunes. Take Bitcoin, for example; the cryptocurrency fell to as little as $5,900 in the past 24 hours before rebounding to just over 6,000 as of this writing. As recently as May, Bitcoin was trading at around $10,000 and in late 2017, it was topping $19,000. In total, Bitcoin is down 68 percent from its meteoric high. Things are looking worse over in Ethereum... Read more...
MyEtherWallet confirmed on Twitter that hackers hijacked its Domain Name System (DNS) servers and redirected users to a phishing site in Russia. By obtaining private keys from affected users, the hackers reportedly were able to swipe around 215 Ethereum coins (ETH) worth somewhere in the neighborhood of $150,000. The attack lasted for several hours, and one user in particular lost more than 85 ETH worth almost $60,000. In the Twitter post, MyEtherWallet emphasized that the security breach did not take place on its side of the equation, and that it's currently in the process of verifying exactly which servers were hit so it can resolve the issue. In the meantime, MyEtherWallet is advising users... Read more...
When it comes to cryptocurrency mining, many small- and large-scale outfits have cornered the GPU market, buying up large quantities of current generation AMD and NVIDIA graphics cards. Gamers have especially been hit hard by miners, as even mainstream graphics cards that should be heading towards the bargain bin at this stage in their lifecycle are priced above MSRP. However, it looks as though Intel might have come up with a solution for a way to more efficiently mine for cryptocurrency instead of using hardware that was originally designed for an unrelated task. Intel's patent was filed on September 23, 2016 and was published by the U.S. Patent & Trademark Office yesterday. The patent... Read more...
Ethereum has taken a swift kick to the blockchain after the Securities and Exchange Commission (SEC) announced that it has "dozens" of investigations open in the cryptocurrency space associated with ICOs (Initial Coin Offerings). The announcement of the investigations was made by an agency official on March 15. The confirmation that the investigations have been opened comes after SEC Enforcement Division co-Director Stephanie Avakian announced in February that subpoenas had been sent to firms that were believed to have broken securities laws. SEC scrutiny of ICOs (initial coin offerings) has grown significantly since billions of dollars in digital assets were sold during 2017, many of which were... Read more...
Plattsburgh, New York is city that has just over 30,000 residents, and those citizens recently saw their power bills unexpectedly increase due to a problem that is starting to affect more people in the United States. We're talking about cryptocurrency mining, of course. Plattsburgh has placed an 18-month ban on new commercial cryptocurrency mining operations after the city was forced to buy additional power to keep up with demand, in turn causing everyone's rates to go up. For gamers, the rise in cryptocurrency mining means that the hot graphics cards that we'd like to get our hands are hard to find and often priced through the roof. However, not everyone needs a graphics card. But electricity... Read more...
Google is taking a stand against advertisements on the internet that promote cryptocurrencies, cryptocurrency exchanges/wallets/trading advice and/or initial coin offerings (ICO). The tech giant says that it will no longer serve ads through its platforms for these products and services starting in June 2018. "We don't have a crystal ball to know where the future is going to go with cryptocurrencies, but we've seen enough consumer harm or potential for consumer harm that it's an area that we want to approach with extreme caution," said Scott Spencer, Google's Director of Sustainable Ads, in an interview with CNBC. In addition, Google will add the following to its "restricted" list with respect... Read more...
There are plenty of uncertainties and grey areas currently lurking around the cryptocurrency market. From wild fluctuations in valuations, to cryptocurrencies like Bitcoin being used on the black market, to government institutions that are looking to get in on a piece of the action, we're still in the "Wild Wild West" days and far from mainstream penetration. Image Source: Flickr via Sebastian Vital With that in mind, Bill Gates gave his thoughts on cryptocurrencies when asked in a reddit "Ask Me Anything" session that was held on Tuesday. To put it bluntly, he is not a fan... at all. Gates stated: The main feature of crypto currencies is their anonymity. I don't think this is a good thing. The... Read more...
Last November a hacker going by the name "DevOps199" found and exploited a flaw in the code for a subset of Ethereum wallets. That user was able to exploit teh vulnerability and take ownership of an Ethereum code library known as a smart contact. Once the hacker owned that smart contract, it was destroyed leaving about $150 million of Ethereum sitting in users' wallets inaccessible. Researchers have now found a new approach that will find vulnerabilities in smart contracts such as the one exploited last year and patch it before a nefarious user could take advantage of the situation. The researchers claim that they found 3,000 vulnerable contracts with a total worth of about $6 million. "We’re... Read more...
Atari has just announced something that will surprise all the gamers out there who grew up on its consoles and games. The company made a big unveil today and while it's not a new console or game, Atari will actually be minting its own new type of cryptocurrency. The new altcoin type will be called "Atari Token" and no, it isn’t trying to take on Bitcoin. Atari Token won't be worth real money apparently, however, it will be used on a new digital entertainment platform to buy content like video games, music, and movies. The deal was inked by Atari SA, the French firm now holding all Atari properties and Infinity Networks. Technically Atari isn’t implementing the new cryptocurrency,... Read more...
The effect that cryptocurrency mining has had on the graphics card market has been so extreme, very few people could have predicted it. GPUs that were as easy to purchase as a gallon of milk became as hard to find as the hottest deal at Best Buy on Black Friday. In addition to the rarity, inflated pricing has been a real issue as well, with many GPUs costing twice as much (or more) than their intended MSRP. A $649 GeForce GTX 1080 Ti, for example, can currently be had as "cheap" as $900, and that's a relative bargain compared to some of the other pricing we've seen. It's not hard to find the same GPU going for $1,300+ at virtually any e-tailer. One of the saving graces for gamers has been companies... Read more...
When AMD announced its earnings last week, the company made it a point to indicate that it would boost capacity in order to address the GPU supply strain caused by booming cryptocurrency mining demand. Yesterday, it was NVIDIA's turn to release earnings -- which it knocked out of the park, by the way -- and it too is looking to address GPU supply problems. NVIDIA CEO and founder Jen-Hsun Huang during his company's earnings call brought attention to the woes gamers (and cryptocurrency miners) are facing when attempting to purchase a Pascal-based graphics cards these days. "We're working really hard to get GPU down to the marketplace for the gamers and we’re doing everything to advise retailers... Read more...
If you need any more evidence that cryptocurrency mining is hitting primetime, look no further than this latest report that Samsung is looking into get in on the action. Samsung is reportedly producing application-specific integrated circuits (ASICs) for Chinese customers that will be use for Bitcoin mining. The initial report, which comes courtesy of a South Korean publication, cites Samsung officials as the source for this information. The chips allegedly completed the development phase late last year and entered production earlier this month. Samsung already confirmed today during its Q4 earrings call that it will see "benefit from cryptocurrency demand increase." This coincides with comments... Read more...
Update, 2/5/2018: We have a new article posted detailing CyptoNote (Monero) mining performance with AMD's Threadripper processor with a CPU-optimized algorithm, alongside a handful of other X86 processors and a powerful GeForce GTX 1080 Ti GPU. Update, 9/15/2017: We've updated our Ethereum mining benchmark numbers in this article to include AMD's recently released Radeon RX Vega graphics cards. Head here for that updated data or journey on for the full guide.  Cryptocurrency mining is a big buzz topic in technology these days. And why not? Utilizing your computer to digitally mine what seems like free money only begs the question, "where do I sign up?" Your machine will actually be... Read more...
After witnessing Bitcoin's explosive growth, everyone and their uncle is now getting into cryptocurrency mining, some for extra money and others in hopes of striking it rich. There are now more than a thousand cryptocurrencies out there. With new miners now showing up in droves (and existing ones expanding their operations), the collective power consumption could be on track to outpace the needs of electric vehicles. Morgan Stanley analysts led by Nicholas Ashworth wrote in a note that cryptocurrency mining could require up to 140 terawatt-hours of electricity in 2018. To put that into perspective, that figure is in line with the total electricity consumption of Argentina, and is 0.6 percent... Read more...
Early yesterday morning, we brought you news of a YouTuber that managed to get his hands on one of the first NVIDIA TITAN V graphics cards that shipped to well-heeled customers. BitsBeTrippin' slapped the chest thumpin' Volta-based GPU into an AMD Ryzen Threadripper 1950X system, and cranked out 70 MH/s at stock speeds and 77 MH/s while overclocked, while drawing 213W and 237W respectively. We here at HotHardware just so happen to have a TITAN V in house as well, and we are presently running it through an exhaustive battery of benchmarks. However, we were able to extract a few data points for all of you Ethereum miners out there. Using Claymore Miner (v10.2), we were able to hit 69.06 MH/s at... Read more...
We know that NVIDIA's TITAN V is a massively powerful videocard, one that we are a thousand percent confident can run Crysis, so no need to ask. But will it blend? Probably. That just leaves one question to answer—how well does it mine cryptocurrency? Pretty darn good, as it turns out. As in, almost double the mining performance (of Ethereum) of an AMD Radeon RX Vega 64 graphics card. YouTuber BitsBeTrippin' installed the TITAN V in a decked out system, swapping out a pair of GeForce GTX 1080 Ti graphics cards, and put the card to the test. The setup also consisted of an AMD Threadripper 1950X processor, ASUS ROG Zenith Extreme motherboard, Corsair H110i cooler, 64GB of G.Skill Trident... Read more...
Christmas is coming early for long-term investors in Bitcoin. The red-hot cryptocurrency has skyrocketed during 2017, most recently crossing the $9,000 threshold on Sunday. At the time, we opined that Bitcoin could be well on its way toward hitting $10,000 by the end of the year. Well, we barely made it 48 hours and Bitcoin is within a stone's throw of $10,000. The cryptocurrency hit a high of $10,086 today, before settling down to $9,950. Bitcoin is up nearly 900 percent so far this year. It seems inevitable that Bitcoin will surpass $10,000 across all exchanges sooner rather than later, allowing it to cross a big psychological barrier and hopefully push further into the mainstream financial...

If you've been following cryptocurrency news over the past few months, then you know that Bitcoin has been on an incredible winning streak. On August 26th, Bitcoin was at $4,300. Three months later, Bitcoin's price has more than doubled. At this moment, Bitcoin has breached yet another high, sitting at $9,065. At the beginning of the month, Bitcoin crossed the $7,500 threshold and hit $8,000 just over a week ago. Today's milestone shows that Bitcoin's growing momentum could allow it to hit $10,000 by year's end. This latest push means that Bitcoin's market cap is now sitting at $151 billion.

If you recently jumped on the Ethereum bandwagon, you might want to sit down for this news. A security vulnerability has been discovered in the Parity wallet service deployed by Parity Technologies. According to a security alert issued by Parity Technologies today, the vulnerability was found within the standard multi-signature (multi-sig) wallet update that was deployed with the Parity Wallet back on July 20th. A multi-sig setup requires that more than one key be used to both initiate and broadcast ETH transactions. What's astounding is the July 20th update was rushed into place after another exploit earlier in the month resulted in roughly $30 million in ETH being stolen from wallets. For its... Read more...
Something big is happening in the cryptocurrency market. Ethereum, the second largest digital coin behind Bitcoin, is receiving a major change to its codebase on Sunday, and nobody knows what exactly will happen. The update amounts to another hard fork, which for the most part have gone well for Ethereum miners and its investors. But there is always that unknown. "I expect that nothing will happen," Ethereum Foundation developer and designer Alex Van de Sande told CoinDesk. "Nothing happened with previous hard forks, except for one."Image Source: Flickr (BTC Keychain) The exception Alex refers to is when an emergency hard fork this past summer resulted in part of the Ethereum community mining...
